This document is intended to be used in any sector of activity. It specifies: — contents of command-response pairs exchanged at the interface, — means of retrieval of data elements and data objects in the card, — structures and contents of historical bytes to describe operating characteristics of the card,. ISO/IEC 7816 or EMV 4.3 integrated circuit card. The design separates the control regis-ters and bus interface from the core logic, which allows you to redefine the register inter-face to meet your specific requirements. General Features: - Technology-independent Verilog HDL implementation. - 8-bit APB host interface. - 8-byte receive buffer. ISO 7816-5 PDF - STANDARD. ISO/IEC. Second edition.

This part of ISO/IEC 7816 supports the following two categories of files : Dedicated file (DF) Elementary file (EF) The logical organization of data in a card consists of following structural hierachy of dedicated files : The DF at the root is called the master file (MF). The MF is mandatory. ISO IEC 7816-15 PDF - Partie Application des informations cryptographiques. STANDARD. ISO/IEC. Reference number. ISO/IEC (E). ISO/IEC (E)..
